They really got dried out, especially that one on the left. I've hatched plenty of snake eggs- not BPs- & I've seen some (similar to yours) that manage to rehydrate & be okay, so don't give up- just wait & see. Did you candle them? I always do- & rechecking them in a few days or in a week will tell you more- some viable eggs don't show much color right away. Time will tell.Keep your fingers crossed- good luck! Some or all could make it, IMO- but it can take a while for them to plump up.
